Adaptix  filed two new suits against HTC alongside wireless carriers AT&T and Verizon. Both cases involve two patents related to OFDMA communication (6,947,748, 7,454,212) and accuse HTC mobile handsets of infringement. Adaptix has asserted these same patents against a number of other mobile device manufacturers, including BlackBerry, Huawei, and ZTE, along with the service providers that sell those phones. The patents are part of a larger portfolio that Adaptix has been asserting since 2008. The entity’s litigation campaign significantly increased after it was acquired by Acacia Research in 2012. The patents-in-suit originated with Broadstorm Telecommunications and were transferred to Adaptix in 2004. RPX reviewed the asserted patents and the portfolio to which they belong in an open market opportunity in May 2011. 5/21, Northern District of California, 4:14cv02359, 4:14cv02360
